-The degree and low degree of a polynomial can be obtained using the two

+The degree and low degree of a polynomial in expanded form can be obtained
+using the two methods
@example
int ex::degree(const ex & s);
int ex::ldegree(const ex & s);
@end example
-which also work reliably on non-expanded input polynomials (they even work
-on rational functions, returning the asymptotic degree). By definition, the
-degree of zero is zero. To extract a coefficient with a certain power from
-an expanded polynomial you use
